GAS-LAMP.

Be it known that I, Thomas J. LITLE, Jr., of Wioodlnu-y, i i the county of Gloucester and State of Xew Jersc have invented a new/Jnduseful'Gas Lantp,of which the fo1- lowing is a-full, clean-and exact description, 1

reference beingfha d"'to the accompanying are'detail viewsshowing one of the Bunsen pipes or tubes; andFigs. 6 and 7 are detail views hereinafter referred to."

-My invention has relation incandescent gas lamps bf the inverted c1uster type',the

main objectof my invention being to pro-' v-idea lamp of this character having the I Bunsen tubes projecting outside of the lamp casing with the adjusting, screws for-the valves readily access ble from the exterior of the 1 amp toprovide an improved construction and arrangementof the Bunsen tubes 'where-. by they may be readily removed for-cleaning or other purposes 'without disturbing the. burners or mantles j to provide means for preventing undue heating of the Bunsen tubes and of the adjusting "screws for the valves .and to provide means for preventing flashbacks at the inletorifices oi the Bunsen tubes and to improve the general construc-' tion and arrangement ofthese and other fea- D ch mneys '17., v The gas way into the valve tures of the lam scribed.

p, as hereinafter fully de- The nature of iny invention will be best I frcx etst oo'd by reference to the accompany-' L'Qm' drawings. in which I have shown one I m bod'iinent thereof, and which will nowbe deseribeiit being pre' nised, however, that various changes may be made in the details its l end c st t'ion and arrangement of the .jbitrtgfwit hout departing from the spirit and{ cqpe ;of1:y invention, as defined in the en"; Jie i Application'filed may 3, 190av senal m. 493,452.
